Best Document Signing Apps in India [2026]: 9 Compared

The best document signing app for most people in India is one that supports Aadhaar eSign, because Aadhaar eSign and DSC are the two electronic signature methods the IT Act specifically recognises. This guide compares nine apps on what matters in India: Aadhaar eSign support, whether you need to install anything, how pricing works, and who each app suits. It is updated for 2026.

What to Look for in a Document Signing App in India

• Aadhaar eSign or DSC support. Section 3A of the IT Act, 2000 recognises electronic signatures made with the techniques listed in its Second Schedule, which include Aadhaar eSign and DSC. A simple typed or drawn e-signature can still be used as evidence of agreement, but it does not carry the same statutory standing. For a deeper look, see Aadhaar eSign legal validity.
• No install for signers. Most of your signers will sign once, on a phone. A browser-based flow beats asking them to download an app.
• Multiple signers. Can you send one document to two or more people and get them to sign in order?
• Pricing model. Per signature, per user per month, or custom enterprise contracts. Light users pay far less on per-signature pricing.
• Proof of signing. Can you download a record of who signed and when?
• API access if you want to build signing into your own product.

1. SignYu

Best for: individuals, landlords, HR teams and small businesses that want Aadhaar eSign without a subscription

SignYu is built for Indian documents. You upload a PDF, add each signer's name, mobile number and email, and SignYu sends them a signing link. Each signer opens the link on any phone or computer, is taken to the licensed eSign gateway (eMudhra), verifies with an OTP on their Aadhaar-linked mobile, and the signature is applied to the PDF. SignYu never asks for or stores Aadhaar numbers; that step happens on the gateway.

Key features:

• Aadhaar OTP eSign through eMudhra
• Multiple signers in a set order
• Signed PDF emailed to everyone, plus a downloadable signature completion certificate with the signing history
• Signer replies go to the sender's email
• Free document templates for common Indian documents
• REST API with SDKs for Node and Python

Pricing: ₹15 per signature, GST included. Credits never expire and there is no subscription. API access is ₹999 per month with a 3-day free trial. See pricing.

Mobile: Works in any mobile browser; no app needed

Is There a Free Document Signing App in India?

Free tools exist, but they usually give you a typed or drawn signature, not an Aadhaar eSign. Each Aadhaar eSign goes through a licensed eSign service provider, which is why apps that offer it charge per signature or include it only in paid plans. For a document where Indian legal standing matters, such as a rent agreement, offer letter or loan agreement, paying for Aadhaar eSign is usually worth it. Our guide to free vs paid Aadhaar eSign covers the trade-offs.

Digital Signature App or eSign App: Which Do You Need?

A "digital signature" in Indian usage often means a DSC: a certificate on a USB token or in the cloud, needed for MCA, GST and income tax filings. An Aadhaar eSign is a one-time signature certificate created on the spot after OTP verification. For everyday documents such as agreements, letters and declarations, Aadhaar eSign is faster and needs no token. For statutory filings, you need a DSC. See DSC vs Aadhaar eSign.

Which App Should You Choose?

• Signing a rent agreement, offer letter or affidavit: a per-signature Aadhaar eSign service such as SignYu. Start with rent agreement eSign or offer letter eSign.
• An HR team sending many letters a month: SignYu for simple per-signature costs, or Zoho Sign if you already run Zoho People.
• A lender or NBFC: Digio or Leegality for KYC, mandates and stamping.
• A global company with Indian operations: DocuSign or Adobe Acrobat Sign for global workflows, plus an Indian Aadhaar eSign provider where needed.
• A developer adding eSign to your product: compare the APIs from SignYu, Digio and Leegality. See the SignYu eSign API for endpoints, SDKs and pricing.

Frequently Asked Questions

Which is the best app to sign documents in India?

For most individuals and small businesses, an Aadhaar eSign service with per-signature pricing, because it is recognised under the IT Act and signers need nothing but their Aadhaar-linked mobile. Large teams with complex workflows may prefer Zoho Sign, Leegality or Digio.

Do signers need to install an app?

Not with most Indian eSign services. SignYu, Leegality and Digio all work in a mobile browser. Signers open a link, verify with an OTP and sign.

Is an Aadhaar eSign legally valid?

Yes. Aadhaar eSign is a recognised electronic signature under Section 3A and the Second Schedule of the IT Act, 2000. It cannot be used for documents excluded by Schedule I, such as wills, powers of attorney and sale deeds.

How can I check that a signed PDF is genuine?

Open it in a PDF reader such as Adobe Acrobat Reader and look at the signature panel, which shows who signed and whether the file has changed since. See how to verify Aadhaar eSigned documents.

How much does it cost to eSign a document?

On SignYu, ₹15 per signature, so a two-party agreement costs ₹30. Subscription apps charge per user per month, often with Aadhaar eSign billed on top.
